THE UK - I do believe it! My catchphrase in One Foot In The Grave may be "I don't believe it" but I almost never use it - and I truly hope I don't have to when it comes to Scotland's future.

Instead when I think about Scotland I prefer to say: "I do believe in the union, I do believe in a unified Britain." That's what I truly believe - that we should be together. As the Scots decide on their future, I am staying positive and hoping that they will choose to preserve our family of nations and stay with us.

On September 18 Scotland will vote on whether to stay in the United Kingdom or leave to form a separate country. For everyone in the rest of the UK, just as for Scotland, the result of the referendum will have a lasting impact on our identity, our culture and our future.

We have done so incredibly well together in the past and I passionately believe we will carry on doing well together in the future, building on our strengths and reaching new heights. That's why I have joined the campaign Let's Stay Together to keep Scotland with the rest of the UK, joining a host of people - both recognisable and not - to show Scotland we care.

I have been proud to take part in our campaign film which is called You're My Best Friend because Queen have generously let us use the song for our soundtrack.

Our campaign brings together people of all political persuasions and none, from every corner of Britain, from all backgrounds and interests, to say to Scotland: "Stay with us!" I believe Scotland should stay in the union.

I am Scottish and I am very proud of being Scottish but I'm also British and I believe that Scotland, England, Ireland and Wales have a lot more clout together than they do individually. There is a symbiotic relationship - everyone does better when we work together as a team.

I consider myself British. I've lived in England for a very long time but rather than being a nationalist I am an internationalist. I want to broaden horizons and get rid of barriers and I think Scotland becoming independent is a little bit isolationist. It's going backwards rather than forwards. I can understand what they are thinking - I just believe we're better together.

It is true that I don't have a vote on Scottish independence - I am not living in Scotland and I haven't lived there for a long time. However this doesn't change the fact that I care passionately about Scotland - and the rest of the UK - and the people and their future. The union has been going for so long and has been so successful that I think we are far better together.

There are undoubtedly some people in Scotland who think that the rest of the UK doesn't care about both them and their country. But the fact is that there is a huge level of support and goodwill in England and throughout the UK for Scotland and its people. You don't have to live in Scotland to care.

Let's Stay Together is the campaign for everybody outside Scotland who wants Scotland to stay part of the UK, because they love Scotland and they love what we've done together. Our aim is to provide a voice for people in England, Wales and Northern Ireland who may not have a vote in the referendum but care deeply about its outcome.

I am very proud of being Scottish

We want to send a friendly message from the rest of the UK to voters in Scotland: we would like the countries to stay together in a partnership of independent-minded nations. We have been together since before the birth of the USA, the French Republic, the United Nations and the European Union.

And we have done rather well as a family with our uniquely British shared values - kinship, compassion, solidarity, our work ethic, fairness, inclusiveness, freedom of speech, freedom of religion and open-mindedness.

Strangely, when the rest of the world looks at Britain it never sees the British as small-minded, isolated or chippy. But they sometimes say the English on their own can come across that way, and they can say the same about the Welsh and the Scots too. Why is that?

What is it about the British identity that is different to the English identity on its own? Is it because we really are better together? I think most of the rest of the world would say so.

I go back to Scotland regularly and I'm very defensive of the place. If anyone tries to run Scotland down my Scottish genes rush to the fore. For example, I'd support Scotland first in any sporting championship or competition, but if Scotland isn't in it and England is I would support England.

I believe in supporting British athletes and British endeavour. If you asked me what I was, I would say I was British first and then Scottish.

I want to see us becoming more internationalist in general. I'm a European as well as a British person. I believe in the European Union and I believe we should be part of Europe and I would just like Scotland to embrace that and become part of a wider international brotherhood.

I think the UK has a much stronger influence as one unified British voice rather than an English or Scottish voice and I think that economically it makes sense that we should stay together. No barriers, no borders - keep it open.

I do believe in a unified Britain where we can celebrate our differences but strive together for a strong, happy and prosperous future. I hope Daily Express readers will support our campaign.
